摘要： The present disclosure generally relates to apparatus and methods for controlling ventilation and temperature around a light source. A ventilation and temperature control assembly configured to selectively facilitate air circulation in an enclosure around a light source is disclosed. In some embodiments, a temperature sensor may be disposed near the light source. The air circulation may be switched on and off according to temperature measurement of the temperature sensor. In some embodiments, the ventilation and temperature control assembly includes a valve to selectively open and close a flow path in the ventilation and temperature control assembly.

摘要： An adsorbent system including an enclosure having a cavity defining a humidity-controlled environment and a body having or defining a channel therein. The body is coupled to the enclosure such that a first end of the channel is in selective fluid communication with an ambient environment and a second end of the channel is in fluid communication with the humidity-controlled environment. The system further includes an adsorbent material in the channel, wherein the channel and adsorbent material are configured such that inlet fluid flowing from the first end to the second end through the channel is flowable over at least a portion of the adsorbent material, and such that outlet fluid flowing from the second end to the first end is directly flowable over a majority of the portion of the adsorbent material that is flowable over by the inlet fluid, The system further includes a valve system positioned at or adjacent to or in fluid communication with the first end of the channel. The valve system includes an inlet valve portion that is biased to a closed position to generally block a flow of inlet fluid therethrough and that is movable to an open position when a pressure in the channel is sufficiently low relative to a pressure in the ambient environment. The valve system further includes an outlet valve portion that is biased to a closed position to generally block a flow of outlet fluid therethrough and that is movable to an open position when the pressure in the channel is sufficiently high relative to the pressure in the ambient environment.

摘要： A ventilation housing includes a housing and ventilation component. A housing tubular projecting part has a communicating hole between housing inner and outer spaces. The ventilation component has: an attachment member over the projecting part with a contacting inner surface; an attachment member supported ventilation body covering a hole end portion between the inner and outer spaces; and a covering member including peripheral and top parts over the attachment member. At least one ventilation path connects the ventilation body and the outer space. A first contact part between an attachment member outer surface outermost protruding portion and covering member peripheral part inner surface is closer to the inner space than an end portion on the outer space side in a second contact part being a contact portion between the housing projecting part outer surface and the attachment member inner surface.

摘要： A ventilation cap according to the present disclosure includes a body, a ventilation filter, a cover member, and legs. A first vent hole is defined in the body, and the ventilation filter is disposed on the body to cover the first vent hole. The cover member is coupled to the body to cover the ventilation filter, and the legs are formed beneath the body and are spaced apart from each other around the first vent hole. Further, the legs are received in a hole defined in a target housing to be coupled to the target housing, and a second vent hole communicating with the first vent hole is defined in a side portion of the cover member.

摘要： In order to provide a vehicle lamp capable of reliably preventing dust from entering a lamp chamber, this invention is equipped with a lamp housing (10) provided with a breathing hole (15), and a cap (2) provided with a breathing port (23). The breathing hole (15) is positioned above the breathing port (23). A breathing passage (3) is provided between the lamp housing (10) and the cap (2). A projecting part (17) is provided on the lamp housing (10). The tip of the projecting part (17) and the cap (2) form a throttle part (30) therebetween. As a result, this invention makes it possible to reliably prevent dust (4) from entering a lamp chamber (13).
